The physical examination of the skin is a fundamental part of the standard physical exam. It understandably relies on the previous comprehension of the anatomy and physiology of the skin, appendages, and mucous membranes. Mainly, this exam consists of a thorough inspection of the skin of the entire body.
The assessment focuses on identifying abnormal signs on the skin, without passing over commonly missed areas, such as the scalp, orifices, nails, and mucosal surfaces. This exam is crucial because it may lead to the detection of skin conditions through the evaluation of rashes, discoloration, and lesions, but it can also detect signs of underlying systemic diseases.
